purolator is a better proposition than fram.......just make sure that you open the box before you buy, and make sure that it looks physically correct and contains the right hardware. the problem with the m50 motor is that every autoparts place SAYS they sell a filter for it, but when you open the box, it is a screw on filter for a m20 (despite saying m50 in the lookup). i couldn't get an oil filter for my last conventional change, so the filter will have been in there for 7000 miles (on 2 3k mile conventional 10w40 changes.) the german parts place was closed, so i just gave up and reused it.
